A container with 2 5/6 gallons of weed killer can spray 3 5/6 lawns. How many gallons would it take to spray 3 lawns?

Question

someone please explain?

Answer 1

(2 5/6 / (3 5/6) = x/3

3 * 2 5/6 = 3 5/6 * x

3/1 * 17/6 = 23/6 * x

3/1 * 17/6 * 6/23 = x

3/1 * 17/1 * 1/23 = x <--- 6 cancels

51/23 = x

2 and 5/23 = x
